Interlock Jumper Plugs
Several jumper plugs must be installed to maintain the integrity of the
interlock chain. Each jumper plug represents a place where you can
add a custom connection to the interlock chain.
497.05 Hydraulic
Control Panel
Any interlocks connected to the hydraulic control panel will generate a
hydraulic interlock which shuts down the hydraulic power supply.
This type of interlock shuts down all test stations.
• Connector J52 requires a jumper plug to close the interlock chain.
• If J26 is not connected, it needs a jumper plug.
• Connectors J15A–J17C (Remote Interlock Inputs) each require a
jumper plug unless it is being used. Jumper both pins of each
connector.
498 System
Digital I/O
Any interlock connected to the 498 System Digital I/O transition
module can generate a station interlock to disable pressure (the HSM)
to that station.
The 498 System Digital I/O transition module supports:
• Four stations of Hydraulics On digital inputs
• Four stations of Hydraulics Hi digital inputs
• Four stations of Hydraulics Enables
• Four stations of Remote Stop/Run outputs
• Four stations of program interlocks
• Four stations of auxiliary interlocks
• Four stations of 497 interlock inputs
• Four stations of 497 interlock outputs
• Four stations of auxiliary interlock inputs
• Four stations of auxiliary interlock outputs
• Two spare digital inputs
• Two spare digital outputs
The interlock connectors require jumpers under the following
conditions:
